The object of the game is to remove as many of the tiles from the playing board as possible. Tiles are always removed in pairs and can only be removed from the left or right edges. Any tile that is not on a left or right edge is considered blocked and cannot be removed. Note though, that the tiles are arranged in five levels and each level has a left and right edge so there are many more unblocked tiles than first appear.
